Not as easy to apply as I would have liked but if my garage doesn’t flood inthe spring it’s worth it

This product works great. Unfortunately, the pail I received had a good part off it already dried up and unusable. That was a bit disappointing as I was short material to get the job done.

J'ai utilisé ce produit pour sceller une fissure de fondation.

A very thick paste. For this size can, use nothing wider than a 2.5" (6.5cm) FLEXIBLE putty knife; otherwise you'll have little maneuvering room in can. Be very careful not to get this on your skin; it is difficult to remove, short of using something like a scouring powder. On top of the paste in my just-opened can was a 1" wide circle of already hardened paste that further limited access to rest of contents until I pulled it out, getting paste all over my fingers. As you spread it, it tends to pull already-laid paste away. The price is rather high for the amount received and actually usable. Would suggest using the "calking gun" version rather than "spooning out" from the can, for better control, especially if filling cracks or caulking a seam between house and driveway, for example. With tropical rains due tomorrow, it will be interesting to see how this holds up.

I've used this product with great successes before, but this time was with issues. First I ordered black and received white. No biggie, I can still use it for my purposes. Opened up both tubs and went in with putty knife. Got through the center, but most of the top 1/3 of the bucket was solid rubber. I used what I could for my issue. Still didn't complete project, but I will have to figure that out another day. I had to throw the rest into the trash since it was unusable. Like I said, I used this product before with no issue and it worked out great. Maybe I received two bad/old containers. Who knows. But don't be discourage to use this product. It works. Just make sure it is fresh.
